You asked: What are the differences between the leathers for the Eames Lounge Chair? MCL and 2100 Series are our classic leathers. They’re designed to last, with a natural grain that’s ideal for acquiring a rich patina over time. Stow and Prone are our newer leathers from @maharamstudio. They have a more vibrant palette and supple pebbled grain. @eamesoffice | Available in the Americas, Asia, and Australia from Herman Miller and from @vitra in Europe and the Middle East.
